A seedling disease characterized by a yellow stripe extending the entire 
length of the leaves was found rather commonly during the last half of 
May. The cause of this disease is unknown. 
A slight infection of ergot was found on Red Wave wheat in Noble 
County, July 10th., by R. V. Allison. Powdery mildew (Hrysiphe graminis) 
was abundant in the latter part of May, probably owing to the prolonged 
wet weather. The bacterial disease, black chaff, was found in Morgan 
County. 
The Septoria leaf-spot was very prevalent early in the season. Later 
the Septoria on the glumes became widespread. Out of the 596 fields ex- 
amined in the course of the federal cereal disease survey, these diseases 
were found in 133. 
Anthracnose caused by Colletotrichum cereale was reported from 10 of 
the 596 fields above mentioned. <A field very badly affected with anthracnose 
was found near Lafayette, June 26th., by Allison. The affected plants in 
this field were already killed at this time. 
Leaf rust (Puecinia triticina) was as usual very severe in Indiana, espe- 
cially in the southern part of the state. Very heavily infected fields were 
seen in Martin County, May 28th., and in Hendricks County, June 26th. 
Leaf rust was reported from 214 or 35% of the 596 fields examined in the 
federal survey, with an average incidence of 1.4% and a maximum of 75%. 
It is probable that leaf rust occurred to some extent in all fields, however. 
Stem rust (Puccinia graminis) was reported from 202 or 539% of the 595 
fields above mentioned, with an average incidence of 6.2% and a maximum 
of 100%. This rust was not epidemic except in the neighborhood of bar- 
berries. Pipal reports cases of epidemic outbreaks near barberries in 
Randolph, Spencer, Knox, and Lagrange Counties. 
3unt or stinking smut caused by TVilletia foetans was reported from 90 
or 15% of the 596 fields above mentioned with an average incidence of less 
than 1%. Pipal reports that the disease was serious only in the northeast 
corner of the state (Steuben and Lagrange Counties). As to the control 
of the disease it is of interest to note that out of 39 fields planted with seed 
treated with wet formaldehyde, bunt was found in seven and in these cases 
to the extent of not over 1%. Out of eight fields planted with seed treated 
by the dry method (formaldehyde), a trace of bunt was found in 1 field. 
In the 45 fields for which the seed was treated by the hot water method, 
bunt was found in only one field, and only to the extent of 1%. 
This season was especially favorable to loose smut caused by Ustilago 
tritici and the disease was especially prevalent. According to Pipal’s obser- 
vations and to the results of the federal cereal disease survey, it was found 
in 760 fields in the state with an average incidence of about 3% and a 
maximum of 30%. Loose smut was most severe in the area comprising 
the following counties: Morgan, Marion, Hancock, Shelby, Rush, Barthol- 
omew, Decatur and Jennings. The greatest losses were suffered in Shelby 
County where the average infection, according to Pipal, on 33 farms ob-
